The reason for this is that the woman’s belly is still big after the cesarean section, generally related to the uterus has not been restored, intestinal flatulence, abdominal fat deposition and abdominal rectus muscle separation and other factors, at this time the woman should be combined with other specific physical symptoms to determine. 1, the uterus has not been restored: after delivery, the uterus propped up by the fetus can not quickly return to the pre-pregnancy, is still inflated state, it seems that the belly is still big. This is a normal physiological phenomenon after childbirth, the mother does not need to be too anxious, the general recovery of the body needs to last until about 42 days after delivery, pay attention to rest and relaxation; 2, intestinal flatulence: because the caesarean section will use anesthetic drugs, intestinal peristalsis becomes weak, gas transport capacity becomes poor, induced intestinal flatulence, resulting in abdominal bulge, the symptoms of the stomach will disappear naturally with the discharge of intestinal gas. At this time, you can accelerate intestinal peristalsis by getting out of bed and walking, abdominal massage, etc., to promote gas discharge; 3, abdominal fat deposition: if the pregnancy is too rich in nutrition, poor weight control, may lead to a large amount of fat stored in the abdomen. This symptom needs to be reduced by way of postpartum weight loss to make the belly smaller; 4, separation of the rectus abdominis muscle: if the mother is also accompanied by symptoms such as back pain, constipation, leakage of urine, etc., the separation of the rectus abdominis muscle needs to be considered. Due to the excessive weight of the fetus and other reasons, so that the abdominal muscles can not maintain the original shape, whenever the force, the abdominal muscles show the outward strip bulge. The abdomen can be restored to its original shape by abdominoplasty. In addition, patients can learn the gentle movements of abdominal support to narrow the gap of the rectus abdominis muscle.
